Wireless microphone

Abstract

A wireless microphone transmits audio signals using infrared rays. A plurality of infrared light emitting devices are attached to a board in the wireless microphone, and at least one of the plurality of infrared light emitting devices is disposed on each side of the board. A plurality of infrared light emitting devices may be provided on each side of the board, and the infrared light emitting devices may be disposed radially. Without providing a different dedicated board for the light emitting devices than the board, infrared rays can be radiated to an area around the mic. In this manner, a wireless microphone is provided that can radiate infrared rays to an area around the mic and that has a simple structure and a small number of components and thus can improve productivity.

1 - 9 . (canceled) 
     
     
         10 . A wireless microphone that transmits audio signals using infrared rays,
 wherein a plurality of infrared light emitting devices are provided on each side of a board in the wireless microphone, and the infrared light emitting devices on both board surfaces are disposed radially,   further, a number of the infrared light emitting devices is set according to directivities of the infrared light emitting devices such that a radiation range covers all directions, and the plurality of infrared light emitting devices are disposed to be spaced from each other in a circumferential direction,   and wherein the wireless microphone comprises a reflecting wall between adjacent infrared light emitting devices, the reflecting wall reflecting infrared rays from the infrared light emitting devices on both sides.   
     
     
         11 . The wireless microphone according to  claim 10 , wherein the infrared light emitting devices disposed on one side of the board and the infrared light emitting devices disposed on an other side are offset in a direction along the board surface. 
     
     
         12 . The wireless microphone according to  claim 10 , wherein the infrared light emitting devices are attached so as to be inclined with respect to the board such that each infrared light emitting device is oriented to an elevation angle direction in a mic position taken when the mic is used. 
     
     
         13 . The wireless microphone according to  claim 10 ,
 wherein a guide member is attached to each side of the board, and the infrared light emitting devices are attached to the board with the infrared light emitting devices disposed on their corresponding guide members, each guide member regulating positions and directions of corresponding infrared light emitting devices,   and wherein each of the guide members has a guide base portion attached to the board; and a light emitting device holding portion connected to the guide base portion by an elastic hinge, and the light emitting device holding portion has a structure that the light emitting device holding portion pivots via the elastic hinge to hold corresponding infrared light emitting devices.   
     
     
         14 . The wireless microphone according to  claim 13 , wherein a visible light emitting device is disposed on the guide members, and the visible light emitting device emits visible light through an infrared pass-through member provided around the infrared light emitting devices.
